The high tensile strength of the material combined with the hard coating on all high wear areas means a much longer duty life than common cast pulleys with no chance of any type of fracturing or structural failure. All pulleys and brackets have a "No Polishing" maintenance-free clear powdercoating. An adjustable stainless steel tensioning rod with chrome-moly rod ends and mounting hardware is also included. There are two pulley ratios available; Performance to increase horsepower by reducing accessory drag, with typical gains of 12-15 horsepower at the rear wheels and High Waterflow to increase cooling by speeding up water flow and fan speed, critical for low speed driving where most overheating occurs.
